// Bulk action bar — the floating "N selected" strip with one icon button per
// bulk action (primitives/MultiSelectBar.slint).
//
// PROMOTED from views/local/LocalMultiSelectBar.qml, unchanged except for the
// import depth. The Slint component it ports was already shared — Local Library
// mounts it for Albums (LocalLibraryView.slint:1239) and Tracks (:1406), and
// the MyQBZ detail page mounts the same primitive (:1253) — so the "Local"
// prefix was a naming accident, not a scoping one. The old
// views/local/LocalMultiSelectBar.qml is GONE — this file is the only copy.
// Call sites: views/local/LocalAlbumsTab.qml, views/local/LocalTracksTab.qml,
// views/myqbz/MyQbzDetailView.qml.
//
// 44px tall, radius 8, surface-elevated: "N selected" on the left, then one
// 34x30 icon button per action — dimmed to 0.4 and disarmed while the action
// needs a selection and there is none, red-bordered when it is a danger
// action. ADR-008: bordered/hover buttons, not pills.
//
// `width` has NO default: every call site anchors or sizes it (the MyQBZ detail
// page uses the .slint's deliberately asymmetric `x: 18` / `width: parent.width
// - 40`). The label Text sizes itself from `parent.width - actionRow.width`, so
// a zero width silently collapses the label rather than the buttons.
//
// The Slint puts the action label in the shared tooltip bubble; the Qt port
// has no tooltip channel into this component, so the label rides Qt's own
// ToolTip. (controls/QbzTooltip.qml is the shell's single hover-tooltip
// overlay, but it is reached by calling showRight()/showAbove() on the
// AppShell instance, which a recycled delegate deep inside a view cannot name.)
